This TrailAir # LC328492 pin box is a match for your trailer if it matches these measurements, or your current pin box is marked "1621".
Compare to attached drawing.
2a: 7-7/8"
2b: 2"
2c: N/A
2d: 5/8"
2e: 15/16"
2f: 6
3a: 17-3/4"
3b: 25-5/8"
3c: 12"
If your measurements match these then the correct Trailair Flex Air 5th Wheel Pin Box for you is part # LC328492 for 18,000 lbs or part # LC369535 for 21,000 lbs.
I have attached links to both of these products and a install video.
